In-House vs Contract Cleaning: The Real Cost Comparison
Key takeaways
- An in-house cleaner's true cost is roughly the wage x 1.25 for on-costs, plus about $2,500 a year for equipment and consumables.
- A contract removes hiring, cover for sick days, insurance and management overhead.
- For most offices, a contract is more cost-effective once the full loaded cost is counted.
For most Adelaide businesses, contract cleaning is cheaper and lower-risk than employing cleaners directly once you count the full loaded cost of an in-house wage. A cleaner's true cost is not their hourly rate: it is the wage multiplied by roughly 1.25 for on-costs, plus about $2,500 a year in equipment and consumables, plus the management time you will never invoice for. Contract cleaning folds all of that into 1 predictable monthly fee, and it hands the cover, insurance, and HR burden to someone else.
The real cost of an in-house cleaner
The headline wage always understates the cost. On-costs (superannuation, workers compensation, leave loading, payroll tax where applicable) add roughly 25% on top of the base wage. So a cleaner you pay $30 an hour actually costs your business closer to $37.50 an hour before they have touched a mop.
- Wage x 1.25 for on-costs: super, workers comp, annual and personal leave, leave loading.
- Equipment and consumables: around $2,500 a year for a vacuum, machinery, chemicals, and stock.
- Recruitment, induction, and training time when the role turns over.
- Management overhead: rostering, supervising, and covering gaps when someone is sick.
Take a small Adelaide office needing 10 cleaning hours a week. At $30 an hour that looks like $15,600 a year. Loaded at 1.25 it is closer to $19,500, and adding equipment pushes it past $22,000 before any management time. The wage was never the real number.
There is also a lumpy capital cost people forget. A commercial vacuum, a mop system, a floor machine for hard floors, and an ongoing supply of chemicals and cloths do not appear in the wage line, but they are real money leaving the business. Machinery wears out and needs replacing, and a directly-employed cleaner rarely has the buying power to source consumables at trade rates the way a contractor servicing many sites does.
What contract cleaning actually costs
Contract cleaning in Adelaide runs $35 to $55 per hour per cleaner for recurring work, and that rate already includes wages, on-costs, insurance, equipment, and supervision. A small office under about 150 sqm cleaned weekly typically costs $60 to $120 per visit. A medium office of 150 to 400 sqm cleaned 3 times a week usually lands at $150 to $350 a week.
The rate looks higher per hour than a bare in-house wage, but you are comparing a complete service against a raw number. Once the in-house wage is loaded and equipped, the gap closes sharply, and often reverses, because the contractor spreads fixed costs across many clients.
Run the same 10-hour-a-week office as a contract. At the mid of the band it sits in the region of the loaded in-house figure, but with 1 difference that matters: the number is fixed and complete. There is no equipment to buy, no leave to fund, no replacement to recruit, and no surprise the year a machine dies or a cleaner resigns. Predictability has a value of its own, and on a stable site the contract price is usually the lower total once every hidden line is counted.
The benefits that do not show up in the hourly rate
Cost is only half the decision. The bigger reason Adelaide businesses move to contract cleaning is that it removes work and risk from your plate entirely.
Cover you never have to arrange
When an in-house cleaner is sick or on leave, the office simply does not get cleaned unless you scramble. A contractor guarantees cover, sending a replacement so the standard holds regardless of who is away.
Insurance and liability handled
The contractors we match carry their own public liability insurance and manage their own workers compensation. If a cleaner is injured on your site or damages property, that sits with the contractor, not with you.
No HR, no rostering, no payroll
- No employment contracts, timesheets, or payslips to run.
- No performance management or awkward conversations about standards.
- No leave to track or superannuation to remit.
- No recruitment when a cleaner moves on; the contractor simply replaces them.
When in-house can still make sense
In-house occasionally wins for very large sites that need a full-time presence all day, where a directly-employed day porter gives more control and a constant on-site response to spills and messes. It can also suit organisations with unusual security requirements that prefer a known, vetted employee over any external party. These are the exceptions, not the rule.
How to make the decision honestly
- Load your in-house wage properly: multiply by 1.25 for on-costs before you compare anything.
- Add roughly $2,500 a year for equipment and consumables to the in-house figure.
- Add an honest estimate of the management hours the role costs you each month.
- Only then put the fully-loaded in-house number next to a contract quote on the same scope.
